dc.description.abstract

Charleston County and the City of North Charleston will experience increasingly severe
flooding due to climate change in the coming century. Modeling potential flooding
extents caused by sea level rise, riverine flooding, and extreme precipitation can be used
by local municipal and community decision makers to protect both people and property.
Flooding models using a one-meter digital elevation raster, hydrologic soil groups,
impervious surface areas, and designed storms were created in ArcGIS across multiple
scales (county and neighborhood) and for multiple recurrence intervals to show the likely
extent of flooding for the neighborhoods represented by the Lowcountry Alliance for
Model Communities (LAMC). Intersecting these modelled floods with U.S. Census block
groups and FEMA designated critical facilities shows the potential risk and where
community, city, and county can most effectively mitigate the hazard.
